Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple specialized devices are used for different reagent strips, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal reader device that can read multiple types of reagent strips through an automated identification system. The cartridge assembly includes an identification code that the reader detects to automatically configure the appropriate reading parameters, allowing one device to perform functions previously requiring multiple specialized devices while maintaining measurement precision through parameter optimization.
2Ease of operation
If manual exam registration is used, then ease of operation is improved for simple systems, but loss of time increases due to cumbersome registration
Solution Approach 1:
The system performs preliminary actions by pre-configuring identification codes in the cartridge assembly and pre-storing examination parameters in the reader's database. When a cartridge is inserted, the system automatically retrieves and applies the appropriate parameters without requiring manual registration, thus eliminating time-consuming registration steps while maintaining ease of operation.
Solution Approach 2:
The cartridge assembly serves itself by containing an identification code that automatically provides the reader with the necessary examination information. The system performs self-registration through the interaction between the cartridge's identification code and the reader's detection mechanism, eliminating the need for manual operator intervention in the registration process.
3Reliability
If electronic code identifier is implemented, then reliability is improved through automatic identification, but device complexity increases
Solution Approach 1:
The patent introduces an identification code as an intermediary element between the cartridge assembly and the reader. This code serves as a mediator that carries examination parameters and enables automatic identification, improving reliability by eliminating manual input errors while adding minimal complexity through the use of a standardized coding system and automated detection mechanism.
4Loss of information
If standardized data management is implemented, then loss of information is reduced, but device complexity increases
Solution Approach 1:
The system merges data management functions by integrating the reader, cartridge identification system, and parameter storage into a unified automated workflow. Examination results, parameters, and identification data are combined and managed through a single integrated system that automatically correlates all information, reducing data loss and improving integrity while managing complexity through consolidation rather than separate systems.
